⧺ Double Plus
⧻ Triple Plus
or would adding Double Plus be ungood?
Examples:
⋘ VERY MUCH LESS-THAN
⋙ VERY MUCH GREATER-THAN
I have no idea what these should do.
Things like
Superset ⊃
Subset ⊂
Does not contain ∌
etc.
As the name goes. This is a totally awesome package and I've found it very beneficial. Dropping by some ideas to bring its UnicodeMath::Set module to a greater functionality, hth:
define_method('∈') do |elem|
self.include?(elem)
end
define_method('∉') do |elem|
!(self.include?(elem))
end
define_method('∅') do
self.empty?
end
set_spec.rb
it 'defines the membership operator: ∈' do
membership = @primes.∈(2)
expect(membership).to eq(true)
end
it 'defines the non-membership operator: ∉' do
nonmembership = @primes.∉(6)
expect(nonmembership).to eq(true)
end
it 'defines the empty set operator: ∅' do
empty_set = @empty_set.∅
expect(empty_set).to eq(true)
end
